Abstract:
A user device provides, to a content delivery system, a content request for selected media and receives, in response to the content request, a unicast link for receiving the selected media via a unicast stream and a multicast link for receiving the selected media via a multicast stream. The user device presents a first portion of the selected media via the unicast stream and buffers, in a local memory, a second portion of the selected media from the multicast stream. The second portion is later in linear sequence of the selected media than the first portion. The user device discontinues presenting the first portion of the selected media when the first portion would overlap the second portion and present the second portion of the selected media from the memory.
